You can also replace the socket on the NES itself for relatively little, it took me about 20 minutes a couple of years ago and it made it much more reliable.
I’d like to add a different take to this. I have contacted Valve support in the past, clearly stated my problem, and got a response that looked like they read half of my question and responded without reading the entire thing. If the same team that responds to their customer support reads this stuff, which seems crazy, they didn’t bother to understand the problem before responding.
